BAND-CUTTER AND FEEDER FOR THRASHING-MACHINES.

SFECIFIOATION forming part of Letters Patent No. 524,48 4, dated-August14, 1894.

Application filed November 21,1893. Serial No. 491,550. (N modem To allwhom it mag concern:

Be it known that I, JOSEPH HOVEY, a citizen of the United States, and aresident of Florida, in the county of Henry and State of Ohio, haveinvented certain new and useful Improvements in'Grain-Separators; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawlugs, and to the letters or figures of reference markedthereon, which form a part of this specification.

Figure l is a longitudinal vertical section of a portion of a thrashingmachine embody- Figs. 2 and 3 are side elevations of the same fromopposite sides, with the bundle carrier folded back. Fig. 4 is adetailview of the band cutter. Fig. 5 is an end view of the crank shaftwhich actuates the vibratory arms N. Fig. 6 is a detail view of one ofthe rocking levers. Fig. 7 is atransverse vertical section of Fig. 1,taken just back of the band cutter and looking toward the cylinder, andFig. 8 is a detail view of one of the ribs P This invention has relationto certain new and useful improvements in band cutters and feeders forthrashing machines; and has for its object the provision of practicaland efficient means for severing the bands of the bundles as they passfrom the bundle-carrier to the feeder.

further object of the invention is the provision of improved means forsecuringauniform distribution and regular feed of the grain as it passesfrom the band cutters to the separator.

A further object is to improve the general constructlon and arrangementof parts, all as will hereinafter appear.

With these objects in View, the invention consists in the novelconstruction and combination of parts all as hereinafter described andpointed out in the appended claims.

Referring to the accompanying drawings, the letterAdesignates the mainframe of the separator, which may be in general of any ordinaryconstruction; having the extension B of general triangular form, whichforms the through.

entire throat or mouth of the machine. Rising from the side sills a, aof this extension, one at each side, are two posts or uprights G.Secured to the faces of these uprights, near their upper ends, arebearings 11, which support a transverse shaft D, carrying a hollow rollE. Upon this roll E, is fastened a series of knives E, each of which isset somewhat obliquely to the axis of the roll, and at difierent anglesto a plane passing there- Each of said knives has a curved edge 61 whichis of serrated or sickle character, and forms the cutting edge, itscurvation being such that as it revolves it will act with a continuousdrawing stroke. Secured to the frame above this roll E is a sheet metalguard F which extends downward and forward of said roll, and is bentrearwardly underneath the same to the rear thereof, as shown in Fig. 1.Slots are formed in said guard through which the knives work. This guardserves to prevent the grain from being wound around the roll as it isrotated.

G, G designate brackets secured one to each of the posts or uprights 0,below the bearings b, said brackets forming bearings for a transverseshaft G which carries wheels or pulleys fwhich drive the webs, belts orchains G of the bundle carrier H, the discharge end of which issupported by said brackets G, G. Said bundle carrier is cut transverselyat g, and jointed so that it may be folded up back against the mouth Bof the separator when desired. Attached to the discharge portion of thecarrier, near said joint and also to the extension B, one at each side,is a rod or link h.

Secured to the sills a a, just forward of the uprights C, are bearingst', in which is journaled a transverse crank-shaft I, which has a crankI at each end. Upon these cranks are journaled the upper, lateralportions of an inclined, vibratory bottom J whose rear end extends tothe concave J of the separator, and rests and slides upon blocks j,secured to the depending frames j. To close the gap formed by thevibration of the table or bottom J, between it and the concave J i ,ahinged gate or extension J is provided, said gate or extension beingfree to slide upon the flange of ,the concave upon the vibration of thebottom. Secured to the upper face of said table or bottom along itsupper half is a series of ribs K, notched or toothed along their upperedges. These ribs upon the vibration of the table or bottom, serve toshake, loosen, and distribute the bundle after its band has been cut,and also to push or feed it forward and downward.

The depending frames'j above referred to are usually bolted to the underside of the sills a. a, or otherwise secured just forward of thecylinder L, and form the support for the regulating and feeding devicenow to be described.

M designates a transverse crank-shaft journaled in bearings Z and havinga series of cranks Z. ferent directions, or at different angles, as seenin Fig. 5. In the drawings I have shown the shaft as provided with eightcranks, but a greater or less number may be employed. J ournaled on eachof said cranks is an arm N, loosely connected at its lower end portionto the end portion of a rocking lever N, which is fulcrumed upon atransverse rod or barf, a series of such levers being provided, one foreach of the arms N. The upper end portions of said arms N are reduced insize, forming elongated points n which project up through elongatedslots 0 in the table or bottom J, said slots having raised guards O toprevent the grain falling through. The cranks Z have a stroke of aboutfour inches, and the arms N are journal'ed thereon. Upon the rotation ofthe. shaft M,these arms are given a vibratory, oscillating movement,causing their upper portions to play back and forth in the slots 0. Thecranks Z all being at different angles, it follows that no two of thearms N will be in the same position at the same time, and the result ofthis arrangement, in connection with the peculiar fmo-vement of each, Ifind to be very efiective in feeding the grain evenly to the cylinder.The rocking levers N, as shown in Fig. 6 are preferably forked at oneend to embrace the arms N, and at the other end to give them a widebearing upon the fulcrum rod.

P designates the top lid or cover of the feeding chamber which is hingedat its upper forward edge to a cross-piece P connecting the posts oruprights G. On the under face of said lid or cover are triangular ribs Pwidest and thickest at their lower ends, their upper ends terminatingshort of the upper end of the lid or cover. The purpose of these ribs isto aid in breaking up and distributing the bundles.

The vibratory bottom or table may be raised to the position indicated bythe dotted line X- Fig. 1 giving sufficient room to permit a man to workat the cylinder.

R, R designate brace rods from the under side of the forward end of thesills a a to the bolster of the separator. for the vibratory table.

The various parts may be driven as foll'owsz-On one end of the cylindershaft isa S, S are side guards 1 pulley 1 from which runs a belt 2 to alarge pulley 3 on one end of the shaft D which carries the cutter-rollE. On the opposite end of the shaft D is a pulley 4 connected by acrossbelt 5 with a pulley 6 on the crank-shaft 1. Behind the pulley 6 isa sprocket wheel 7 which drives the shaft G by means of a chainbelt 8.Upon the other end of the shaft G is a pulley 9, which drives thecrank-shaft M by means of a pulley 10 thereon and a connecting belt 11.

The operation of the various parts is believed to be fully apparent fromthe above description. Preferably all projecting in dif- Having thusdescribed my invention, what I claim as new, and desire to secure byLetters Patent, is-
